Why does it have to be letters and numbers? You're just making more work. You can use an auto_increment field and not worry about it (assuming MySQL).
You can also use uniqid() and md5() to make a unique string, but it'll be 32 characters long. Maybe crypt() is 16 characters...dunno, but you could try that. www.php.net/uniqid ---John Holmes... > -----Original Message----- > From: Peter [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, May 29, 2002 8:28 PM > To: Php > Subject: [PHP] generating next number... from db extraction > > hi, > > I'm making a quoting system and need to have letters & Numbers inside the > quote number.
